I’m scheduled to pick up my 13 PM this Friday at an Apple store. I’m trade up using IUP so I will be returning my current phone with them. However, I just learned in order to login in WeChat on a new iPhone it requires the old phone to scan the QR code displayed on the new phone, it’s one of the many security features from wechat. In that case does Apple allow you time to restore new phone from iCloud, then login into wechat with help from old phone, then reset old phone to factory settings and finally give them the old phone? My past experiences was they tried to rush you out asap since it’s launch day.
